   4 Subject: [PATCH] fix-glamo-mci-set-default-drive-level-0.patch
   5
   6 Tests on access to SD Card with Glamo drive level "0" show
   7 that it reduces SD_CLK energy at 1.5GHz by 24dBm compared to
   8 drive level 3.  This puts it only 6dB above the background
   9 noise floor compared to 30dB and should make a solution for
  10 GPS trouble with SD Card in.
  11
  12 SD card communication seems unaffected so far on the Sandisk
  13 512MB card we ship.
